Today is the third day of feeding the BSF 1 lb of hog feed/day. This is more food than I've been adding and the activity level in the bin is consistently high. Today at noon I checked the bin and several larvae were trying to exit. The last time that happened it was an issue with temperature, but that was on a much hotter day. I believe that the increased activity of the BSF is creating more heat so I'll have to address that. At the time I saw the larvae trying to leave the sun was hitting the bin directly. It's only in the mid 80's and I think that indicates that direct sunshine should be avoided when placing a BSF container.
